" hBe illwhat Oneobjectofmiy mventlon lSvtO provide of Minneapolis, in the countyof Hennepin and State of Minnesota, have invented certain" new and useful Improvements in Shift ring Mechanisms for Cultivators, of which the following-is aspecificati'on.

meansffor shifting the shovels of cultivators and the like laterally'with respect to the frame of the cultivator Another object of my invention is t0*p1'o-' vide power; operated, means" for shifting cultivator shovels and the like laterally; 1 ;Another object of my invention is to pro vide, in a cultivator having'n eans for raise ing and lowering the shovels, power operated shifting-means .for. moving the shovels laterally with respect to the cultivator frame. a g V With these and incidentalobjects'in View "the invention consists of certain novel features of construction and combination of parts, the essential elements .of which are -hereinafter describedwithreference-to the 7- drawing which accompanies and forms a I the front cross bar 4. by longitudina1 4mempart of this specification. V r In the drawing Figure'lisa plan v1ew of a cultivator embodying my; invention.

Fig '2 is a section taken on'the line 2 '2, v v is aside view showlng "the shovel lifting mechanism with part of "Fig. 1, and Fig.

the connecting link broken away.

In the cultivator-shown in Fig." 17 the frame consists of an axle 1" supporting the crank spindles 2 and 3 and connected to bers 5 and'fi. 1

The hitch and the like are omitted for the sake of simplicity; [as they have nothing-tc i do with my present invention;

A support 7, carried'by the axle has jhingedz. at 8 a bell crank 9 through which the rod .10 passes, and allink 11-, hinged at to the lever 13, providesgmeans for rais- V ing'and lowering the cross rod 10' by the I motion of the lever 13; -L

so the raisingand lowering of the rod '10 will raise and and 21.

The cranks 2 and 3 are mounted to turn I. BnRToN M. Marlins, i -r A "x I a citizen of the United States, and a resieent The rod 10v is journaled insupports carried by the shovel beams 14, 15, 16 and 17 lower the shovels 18 1 9 20;
